Picked these up to use on my Ecosphere set up to improve gas exchange throughout my grow process. The air quality inside the tent smells fresher without reducing my humidity or affecting temperature in a meaningful way.



I love being able to just buy what I need and trust that Midwest has done the homework for me :)

These things are great! They are thick and durable and they stick like grim death.

Great

Great value and fast shipping..

By far the best customer service and shipping time I’ve seen in a while...They will respond to emails right away and have the item shipped out the next day. Also, Injected my bags with spores four days ago and when it’s time I will be definitely be buying my substrate from these guys. 100% satisfied so far!
